Bucketless Carwash Composition

Abstract

A novel car wash composition that significantly reduces water spotting, redeposition of soil, and inhibits the formation of hard water scale. The novel car wash composition is comprised of: a substantive polymer to render the painted surface of the car more hydrophilic, a surfactant package containing a mixture of anionic and non-ionic surfactants selected to optimize the benefits of the substantive polymer, and various fragrances, dyes, and biocides commonly found in car wash compositions.

1 . A car wash composition comprising: 
 a surfactant package, from about 1 to 80% of the composition mass, containing at least one surfactant selected from the group consisting of anionic surfactant, non-ionic surfactant or mixtures thereof; a polymer package from about 0.01 to about 10% of the composition mass, containing at least one substantive polymer capable of bonding with a surface to provide improved hydrophilicity, having a molecular weight from about 5,000 to about 95,000; and from about 10 to about 95% water.    
     
     
         2 . The composition of  claim 1 , further comprising a dye.  
     
     
         3 . The composition of  claim 1 , further comprising a biocide.  
     
     
         4 . The composition of  claim 1 , further comprising a fragrant material.  
     
     
         5 . The composition of  claim 1 , further comprising an alkalinity source.  
     
     
         6 . The composition of  claim 1 , wherein said at least one surfactant is an anionic surfactant selected from the group consisting of sulfates, sulfonates, disulfonates, and sulfosuccinates.  
     
     
         7 . The composition of  claim 6 , wherein said anionic surfactant is an olefin sulfonate.  
     
     
         8 . The composition of  claim 7 , wherein said olefin sulfonate is a sodium alpha olefin sulfonate.  
     
     
         9 . The composition of  claim 1 , wherein said at least one surfactant is an anionic surfactant selected from the group consisting of sulfates of ethoxylates and sulfates of alkoxylates.  
     
     
         10 . The composition of  claim 9 , wherein said anionic surfactant is an alkyl ether sulfate salt.  
     
     
         11 . The composition of  claim 10 , wherein the alkyl ether sulfate salt contains a cation selected from the group consisting of sodium, potassium, ammonium, and an alkyloamine compound.  
     
     
         12 . The composition of  claim 10  wherein the alkyl unit of said alkyl ether sulfate salt is a straight chain saturated organic compound containing from about 12 to about 18 carbon atoms.  
     
     
         13 . The composition of  claim 10 , wherein said alkyl ether sulfate salt contains from 1 to 5 ethylene oxide units.  
     
     
         14 . The composition of  claim 1 , wherein said at least one surfactant is a fatty acid alkanolamide non-ionic surfactant.  
     
     
         15 . The composition of  claim 14 , wherein said fatty acid alkanolamide non-ionic surfactant has a glycerin unit.  
     
     
         16 . The composition of  claim 15 , wherein the fatty acid in said fatty acid alkanolamide non-ionic surfactant is derived from a vegetable oil.  
     
     
         17 . The composition of  claim 1 , wherein said substantive polymer is a sulfonate acrylate copolymer.  
     
     
         18 . The composition of  claim 1 , wherein said substantive polymer is a multi-functional polymer commercially available for use in automatic dish washing cleaning compositions.  
     
     
         19 . The composition of  claim 1 , wherein said substantive polymer is selected from the group of multifunctional polymers consisting of ALCOGUARD 4000 and ALCOSPERSE 240.  
     
     
         20 . The method of washing a vehicle comprising the following steps: providing a car wash composition of  claim 1;  wetting the vehicle surface; applying said composition directly to the said vehicle surface; agitating said composition on said surface of said vehicle with an appropriate material for cleaning said vehicle surface; and rinsing said vehicle surface with water.
